Error while opening editorhttps://www.eclipse.org/forums/index.php/mv/msg/12323/38511/#msg_38511
I've wrote a parser and a dummy AST visitor. Both of them are DLTK
compliant. Now I try to have an editor. In order to do so, I have a
class that extends the abstract ScriptEditor. I extend it as shown in
the python example available there : http://wiki.eclipse.org/DLTK_IDE_Guide:Step_2._Towards_an_Ed itor . Well,
every time I try to open a file threw this new editor, I got an NPE from
an inner class of Script editor. It seems related to completion
process, but I have not required it in any kind. Have I forgotten
something or does it deserve that I report it ?

Regards

PS : Here is the stack trace that occurs when I try to open a source file.
